Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

In a major breakthrough, scientists have observed a strange and previously theoretical form of light — known as negative light. This marks the first time in human history that such a phenomenon has ...

Physicists in the US have demonstrated negative refraction at optical wavelengths for the first time. Vladimir Shalaev and colleagues at Purdue University obtained the result in a material consisting ...

Ether (or aether) is a term used in ancient mythology and medieval science to denote the matter that fills in the void of the universe. In the 19th century, physicists borrowed the concept to depict a ...

The last 15 days before the Grade 10 CBSE Physics examination are meant for smart revision, not new learning. With a clear plan and the right practice, even challenging chapters like Light, Reflection ...
